To all [11710111. it may concern: p

Be it known that l, FnANitE. R SH, a citizen of the "United States, residing at Sullivan, in the county of Sullivan and State of Indiana, have invented new and useful liiiprovemcnts in lVrenchcs, of which the following s a specification.

The present invention relates to improve ments in wrenches, and the'primary ob ectl of the invention is to provide novel and effective means foihthe rapid and easy adjustment of the sliding or movable jaw. I

The invention resides in the peculiar construction and arrangement of parts-and fea tures and in certain parts thereof, substantially as illustrated and as set forth hei"ein-- after.

In the accompanying drawing: Figure 1 is a perspective view of a wrench constructed in accordance with the present invention, F 1g. 2 is a transverse sectional View approximately on the hne22 of Fig. 1,

Fig. 3 is a longitudinal sectionalview on In the drawings, the numeral 1 designates I the shank of the wrench hav ng at one of,

its ends a fixedj aw 2. The movable jaw 3 is slidably mounted upon the shank and is capable of moving the entirelength thereof. The carriage of the inovableja'w has one of its sides provided with a cut-away portion or opening 4 which communicates with one of the sides of the shank lwhen the said shank is arranged in the bore of. the movable jaw and the said side of the shank is provided with transverseteeth Arranged within the opening 4: and filling the sameis a block 6, the said block. preferably having its inner face. provided with teeth 7 which are adapted to engage said teeth when the block is forced toward the teeth 5 of the shank'l. The outer face of the block 6 has either formed therewith or secured thereon laterally extendingsp-ring arms 8 WlllCl'l may be received 1n suitable depressions provided in the carriage of the movable jaw which communicate with the depression within "which the block is received, or the spring 'inenibers, which are centrally arranged'upon the saidblock, may

have theirends around and disposed adjacent the opposite threaded openings 99 provided in the shank of the movable aw. Engaging with the openings 9 are threaded members 10 which secure the bracket 11 transversely of the opening 4 and of theblock 6. Theblock 6 upon its said outer face is provided with a laterally disposed lug 12, the corners of which are preferably rounded, and the said lock is adapted to coact with a substantially rounded kerf or depression 13 provided in the head 14 of an. operating lever 15. The lever has its head arranged within the central and reduced portion of the bar or bracketll and the outer face of the head 14 provided with a rounded apertiue or depression 16 which receives the end of. a set screw 17 provided centrally in the bar or bracket 11, the said screw being provided with a binding nut 18,

so that the contacting engagement of the said screw with relation to the head 14 of the operating lever may be regulated.

It will be apparent that when the handle of the lever-is arranged centrally and longi- I tudinally of the shank of the "wrench, the

kerf 13 and the head 14 thereof will receive the lug 12, so that the spring members acting upon the block will elevate its engaging face out of contact with the teeth 5 of the shank 1, but it will also be apparent that i when the lever is swung to bring the lug out of its kerfto permit of the head bearing against the said lug, the block 6 will be moved within its depression'or openingto have its friction face contact with the friction face 5 of the shank of the stationary jaw.

- From the above description, taken in con nection' with the-accompanying drawings, the simplicityof the device, as well as the advantages thereof will, itis thought, be perfectly apparent to those skilled in'tlie art to which such invention appertains without further detailed description.

Having thus described the invention, what i I claim is:

In a wrench, the combination with a shank having a fixed aw, of a movable jaw slidably mounted upon the shank, said movable jaw having a substantially rectangular I opening communicatingwith'the shank, a

rectangular bloek' filling [and arranged for lateral movement through the opening, said block having an inner frictionface, a spring secured to the block and extending laterally thereofi} the extension of the spring being" rcceivedin depressions in the movable jaw, a lugarranged-centrally of the block upon its outer face, a bar straddling the block 7 i r and its spring'and secured to-the movable jaw, said bar having ra central reduced porrtlOil it lever having its head arranged withinthe said reduced portion of the bar, -the head'of said lever having a'kerf normally receiving the lug'of the friction block, an adjustable means contacting with the head C'opies bf lt h i s nat en t may he obtained for t t v Washington, D. 0.
